Supported decision making is a framework that helps people with disability make their own decisions with support, rather than having decisions made for them by guardians or administrators. It respects autonomy, builds capacity, and empowers individuals to exercise choice and control in their lives.
This guide explains what supported decision making is, how it differs from guardianship, how NDIS funds decision-making supports, practical strategies for implementing supported decision making, and legal frameworks in Australia.
What is Supported Decision Making?
Supported decision making (SDM) is a process where:
- You make your own decisions (you are the decision maker)
- With support from people you trust
- Support helps you understand options, consequences, and make informed choices
- You retain legal capacity and decision-making rights
Core principles:
- Presumption of capacity - Everyone is assumed capable of making decisions unless proven otherwise
- Right to make decisions - Including the right to make decisions others disagree with
- Support to make decisions - Providing whatever support is needed to maximize capacity
- Least restrictive option - Only remove decision-making rights as absolute last resort
Supported decision making is NOT:
- Someone making decisions for you
- Being told what to do
- Guardianship or administration
- Removing your rights
Why Supported Decision Making Matters
Autonomy and dignity:
- Respects your right to direct your own life
- Preserves dignity and self-determination
- Builds on strengths and capacity
Better outcomes:
- Research shows supported decision making leads to:
- Better quality of life
- Higher satisfaction with decisions
- Increased independence
- Stronger relationships
Capacity building:
- Learning to make decisions builds skills
- Confidence grows with practice
- Dependence on others decreases over time
Human rights:
- United Nations Convention on Rights of Persons with Disabilities (CRPD) Article 12 emphasizes:
- Equal recognition before the law
- Right to exercise legal capacity
- Access to support in decision making
- Supported decision making over substitute decision making (guardianship)
Supported Decision Making vs Guardianship
| Aspect | Supported Decision Making | Guardianship |
|---|---|---|
| Who decides | You make decisions | Guardian makes decisions for you |
| Legal capacity | You retain legal rights | Legal rights removed |
| Empowerment | Builds capacity and confidence | Creates dependence |
| Flexibility | Tailored support as needed | Broad removal of rights |
| Reversibility | Support can change or stop anytime | Requires tribunal review to revoke |
| Philosophy | Maximizing autonomy | Protecting from harm |
| Focus | Strengths-based | Deficit-based |
| CRPD compliance | Complies with Article 12 | Inconsistent with Article 12 |
When guardianship might be considered:
- Only as absolute last resort
- When all supported decision making options exhausted
- When person consistently makes decisions causing serious harm AND
- Cannot understand even with maximum support
Current trend: Movement away from guardianship toward supported decision making globally.

Strategies for Effective Supported Decision Making
1. Accessible Information
Strategies:

- Visual supports (photos, diagrams, social stories)
- Videos and demonstrations
- Hands-on experiences (trials, visits)
- Breaking information into small chunks
- Repeat and review information
Example: Choosing NDIS providers:
- Easy Read provider profiles
- Visit providers and see services
- Talk to current participants
- Pictures of staff and facilities
- Summary of key differences
2. Structured Decision-Making Process
Steps:
- Identify the decision - What are you deciding?
- Gather information - What do you need to know?
- Identify options - What are your choices?
- Explore consequences - What happens with each option?
- Identify preferences - What matters most to you?
- Make decision - Choose option
- Enact decision - Put it into action
- Review - How did it go? Adjust if needed
Use visual decision-making tools:
- Decision trees
- Pro/con lists
- Decision boards with pictures
- Timelines showing consequences
3. Communication Supports
For people with communication difficulties:
AAC (Augmentative and Alternative Communication):
- Communication boards or books
- Speech-generating devices
- Apps (Proloquo2Go, TouchChat)
- Sign language or gesture systems
Interpreters and facilitators:
- AUSLAN interpreters
- Cultural interpreters
- Facilitated communication (with safeguards)
Yes/no systems:
- Clear yes/no signals (head nods, thumbs up/down)
- Eye-gaze systems
- Switch systems
4. Time and Repetition
Allow adequate time:
- Don’t rush decisions
- Provide information multiple times
- Give time to process and think
- Circle back to check understanding
Break decisions into smaller steps:
- Big decisions: Break into manageable sub-decisions
- Make one part at a time
- Build confidence with smaller decisions first
5. Person-Centered Planning
Focus on:
- What’s important TO you (your values, preferences)
- What’s important FOR you (health, safety, wellbeing)
- Balancing both
Use person-centered tools:
- PATH (Planning Alternative Tomorrows with Hope)
- MAPS (Making Action Plans)
- One-page profiles
- Communication charts
6. Trial and Error
Learning through experience:
- Try an option and see how it goes
- Review and adjust
- It’s okay to change decisions
- Learn from mistakes (supported)
Example: Choosing between two day programs:
- Trial each for 2 weeks
- Reflect on experiences
- Make decision based on trial
- Can change later if not working
Supported Decision Making Agreements
What is an SDM agreement?
A document that:
- Identifies your supporters
- Specifies what decisions they help with
- Clarifies their role (support, not decide)
- Outlines how disagreements are resolved
Types of agreements:
Informal Agreements
Characteristics:
- Not legally binding
- Flexible and changeable
- Between you and supporters
- No official process
Example: Simple written statement: “I choose my sister Jane to help me make decisions about my NDIS plan and my friend Mark to help me with health decisions. They will provide information, discuss options with me, and help me communicate my decisions, but I will make the final decisions.”
Formal Agreements
Characteristics:
- Documented and witnessed
- May have legal recognition (depending on state)
- More structured process
- Clearer enforceability
Some states have legal frameworks:
- South Australia: Advance Care Directives Act includes SDM
- Victoria: Supported Decision-Making pilot programs
- Other states: Evolving frameworks
Elements of formal SDM agreement:
- Parties: You and your supporters
- Decisions covered: NDIS, health, finances, etc.
- Role of supporters: What they will do (provide info, discuss options, help communicate)
- What supporters won’t do: Make decisions for you
- Duration: Ongoing or time-limited
- Review process: When and how to review
- Dispute resolution: What happens if disagreement
- Witnesses: Independent witnesses to agreement
NDIS Nominees vs Supported Decision Making
NDIS nominees are different from supported decision making:
Plan Nominee
Role:
- Makes decisions about your NDIS plan on your behalf
- Communicates with NDIA
- Approves plan and changes
When appointed:
- Participant cannot make plan decisions even with support
- Often children (parent as nominee)
- Adults with very limited capacity
Key point: Plan nominee makes decisions FOR you (substitute decision making), not WITH you (supported decision making).
Correspondence Nominee
Role:
- Receives and manages NDIS correspondence on your behalf
- Communicates with NDIA
- You still make decisions
More aligned with supported decision making:
- Can help you understand NDIS information
- Support you to make decisions
- Communicate your decisions to NDIA
Difference from plan nominee:
- You make decisions
- Correspondence nominee assists with communication
Transitioning from Nominee to Supported Decision Making
If you have a nominee but want to make your own decisions:
- Discuss with nominee and LAC
- Request nominee cancellation
- Put supported decision making in place
- NDIA must consider if you can make decisions with support before continuing nominee
NDIA’s role:
- Presume capacity
- Explore supported decision making
- Only appoint or continue nominee if necessary
When Supported Decision Making Isn’t Working
Signs SDM may need adjustment:
- You feel pressured or controlled
- Supporters disagree and create conflict
- You’re not understanding information even with support
- Decisions consistently result in harm
- Supporters are acting in their own interest
What to do:
1. Review and adjust:
- Change supporters
- Try different communication strategies
- More time and support
- Professional facilitation
2. Seek advocacy:
- Independent advocate to review process
- Mediation if conflict with supporters
- Legal advice if rights being violated
3. Consider alternatives:
- If SDM genuinely not working after exhausting all options
- Guardianship tribunal may consider limited guardianship (specific decisions only)
- Continue SDM for decisions where it works
Important: Difficulty with SDM is not automatic grounds for guardianship. Tribunals must explore all less restrictive options first.
State and Territory Legal Frameworks
Guardianship Legislation
Each state/territory has guardianship laws:
- New South Wales: Guardianship Act 1987

- Least restrictive option
- Supported decision making preferred over guardianship
Supported Decision Making Recognition
South Australia:
- Advance Care Directives Act 2013 includes provision for SDM
- Can formally appoint SDM supporters
Victoria:
- Guardianship and Administration Act 2019 recognizes SDM
- Supportive Attorney (similar to SDM) can be appointed
Other states:
- Increasing recognition in case law
- Tribunals required to consider SDM before appointing guardians
- Evolving policy and practice frameworks
Frequently Asked Questions
Can I have both supported decision making and a nominee?
Yes, for different types of decisions. For example, you might have a correspondence nominee to help with NDIS communication but use supported decision making for health decisions. However, if you have a plan nominee (who makes NDIS decisions for you), that’s substitute decision making, not supported decision making for NDIS matters.
What if my supporters disagree with each other?
You can have a process for resolving disagreements in your SDM agreement. Options include: you make the final decision (even if supporters disagree), appoint a third person to help resolve conflict, or change supporters if conflict is ongoing. The key is that you remain the decision maker.
Can supported decision making be used in legal situations?
Yes. Courts and tribunals increasingly recognize supported decision making. You can have a support person with you in legal proceedings, use communication supports, and have information provided in accessible formats. Legal capacity to make decisions is presumed unless proven otherwise.
What if my family doesn’t support my decisions?
You have the right to make your own decisions, even if family disagrees. Supported decision making recognizes the right to make decisions others think are unwise, as long as you understand the decision. If family is trying to impose guardianship against your wishes, seek independent advocacy and legal support.
How do I prove I can make decisions with support?
Demonstrate:
- You understand the decision (even if support is needed)
- You can weigh options and consequences (with accessible information)
- You can communicate a decision (using whatever communication method works for you)
- You’re making the decision freely (not coerced)
Professional assessments from psychologists, occupational therapists, or speech pathologists can support this.
Can I change my supporters?
Yes, anytime. Supported decision making is flexible. If a supporter isn’t working out, you can ask someone else to support you instead.
